synthesis and study of modified alkylphenolate additives for motor oils

The article presents the results of research on the synthesis of new medium alkaline aki-31, aki-57, and high alkaline additives aki-124 and aki-134. additives aki-31 and aki-57 are calcium salts of condensation products of dodecylphenol, formaldehyde, and amino acetic (aki-31) or p-aminobenzoic (aki-57) acid. highly alkaline additives aki-124 and aki-134 are carbonated calcium salts of condensation products of dodecylphenol, formaldehyde, and amino acetic acid (aki-124) or p-aminobenzoic acid (aki-134). the high-performance properties of the additives have been confirmed by standard research methods. studies have shown that the additives have high antioxidant, anticorrosive, and detergent properties. highly alkaline additives aki-124 and aki-134 were studied by thermal analysis methods. it is shown that the additives are highly resistant to temperature effects. by using highly alkaline additives, m-10g2 motor oils have been developed, which in terms of basic performance indicators correspond to gost 8581-92 and are on a par with the foreign analog of shell.
